You need to deploy resources into two different regions in the same Terraform configuration using...

Detailed Explanation:Rationale for Correct Answer:When using multiple configurations of the same provider (e.g., AWS in different regions), Terraform requires the use of an aliasto distinguishalias argument:provider " aws " { alias = " west " region = " us-west-2 " }This allows resources to explicitly reference the aliased provider using:provider = aws.westThis is the standard Terraform pattern for multi-region or multi-account deployments.Analysis of Incorrect Options (Distractors):

Answer: Resource block only — Incorrect because it does not define how to use a different region; it relies on provider configuration.

Answer: provider " aws " " west " — Incorrect syntax; Terraform does not support naming providers this way. The correct method is using the alias argument.

Answer: provider " aws_west " — Incorrect because provider names must match actual providers (e.g., aws). You cannot invent a new provider name. Key Concept:Provider aliasing enables multiple configurations of the same provider (e.g., multiple AWS regions).
